2007 GMC Sierra--ABS/Brake lights still on

Post by **mikel** » Thu Jun 14, 2012 3:03 pm

were still investigating why other changes are being made when you write a tune,.
It is isolated to 07 models, but we are looking into it.

Thanks

Can u tell me is the problem specific to the intune or is it it present in the trinity as well?

its specific to 07 trucks....not to any tool.

Ok so basically it wouldn't make a difference if I upgraded to the trinity. That's what I was getting at. Thanks again. Keep
Me updated guys.

Yup Adammannis I feel you. Its kind of annoying being a GM mastertec and I cant fix my abs and brake light on problem because its a software Issue. I have the same problem!!!

I promise, we're still actively looking into this and why it ONLY happens to certain 07 models...

My 08 does this too so its not just 07. I got my intune today and loaded the 87 octane and stiffer shifting and calibrated for my 285/70/17 tires and got the lights. I cleared it back to factory on the side of the road and tried to only change tire size but when it automatically asked if i wanted to update the tcm after doing the ecm i hit yes not really thinking about it at the time but then the lights came on again. I thought maybe tuning the tcm without actually changing anything might have messed with it so i set it back to factory again. Then i decided to change the tires again and hit no on the tcm update but didn't help. Lights came back on and i cleared it back to factory and hoped i just needed to update the unit but it is up to date running version 1r02a, tune DB 1r01f, PID DB 1r01a so now I'm searching and kinda bummed after reading this.

So do you garranty that it is just a glitch and won't mess anything up using the tunes? I have a road trip next week and would like to know how fast I'm going on a 12 hr round trip and I don't foresee this issue being resolved by the end of this week.

yes, its a simple glitch, affects nothing else...
